ECR Energy City Graz-Reininghaus: Urban strategies for the new conception, construction, operation and restructuring of an energy self-sufficient city district
The aim is the development of a valid set of specific values and a guideline as a basis for energy self-sufficient district development. Based on the results, a masterplan (energy-network) for the district Graz-Reininghaus shall be developed. Future-oriented "city-building-blocks" will be implemented as flagships of innovation.
The focal points of the largest urban development project in Europe are the topics public space and microclimate as well as cross-building energy supply. Landmark projects will be implemented in the areas residential buildings, office/industry buildings and mobility.
Conversion of an attic of a typical building from the period about 1900 to a passive attic with photovoltaic system and renovation of the existing building equipment. The aim is to keep the additional construction costs under 10 %, to avoid overheating in summer and to make possible a reproduction for the large amount of buildings from the same period.
Climate neutral buildings from the period of promoterism - ways, potentials and possibilities of implementation
The focus was on the goal-oriented and economic options, in order to achieve a CO2-neutral energy supply and hermetically sealed building envelope as well as to show high energy efficiency when using. On the other hand building protection regulations and the quality in use are to be considered.
Research, development and realization of integral building concepts in passive house quality!
Passive House refurbishment facade with integrated photovoltaic modules for direct, current-based warm water preheating. The GIWOG, an energy-conscious and environmentally and socially oriented client, intends to undertake an energy-related modernisation project, which will further optimise energy consumption to be more efficient at an apartment complex in Graz, main street 302-306. The goal is to lower the energy consumption for heating and hot water from the current level of approximately 135 kWh /m²a to approximately 8 kWh /m²a. The planned measures should correspond with an overall energy consumption reduction of approx. 94 %.
Sophisticated implementation of different passive house-building services systems on a basis of four similar parts of a structure of multi-storey dwelling houses.
Whiscers is a system for installing internal wall insulation with minimal mess, whilst the resident remains in the property. It involves measuring the walls in the property using a laser device that enables fast and highly accurate measurement. Information is then sent electronically to a computer controlled off-site cutting machine that is rapid, precise and mess-free.
Innovation & Cost efficiency: Building standards for multi family residential buildings at optimal cost (Inno-Cost)
In this project, innovative building standards were examined concerning their economical aspects through the life cycle of a building. By means of life cycle-costs for 40-50 multi family lowest energy and passive house residential buildings on actual data from the day-to-day operation, reliable data and know-how was compiled for the first time, which is to support further market penetration of innovative building standards in the field of multi family residential buildings.
Alongside the realisation of the plus energy building in Kapfenberg, a demonstration project is scheduled to be created that accomplishes an economically viable and technically innovative solution for the future.
Multi-Activ-Facade is a pre-manufactured, multifunctional panellised façade, which incorporates ventilation with heat recovery, passive house windows and photovoltaic for smart self-supply within retrofitting measures. The specific challenge is the application within social housing.
OPEN LIVING PLUS - building structures and utilization options with high social functionality and plusEnergie-standard for rural regions
In small to medium sized communities in rural Regions there is a high demand for sustainable building and space for innovative living facilities, to satisfy the requirements of current and coming life designs. The project’s intentions were to provide social scientific groundwork, develop building structures and utilization options of high social functionality and to transfer knowledge to decision makers in communities and regional authorities.
Refurbishment of single- and two-familiy houses in timber construction in Austria has a large CO2-saving potential. To meet the special requirements for the refurbishment of timber constructions, a concept for the renovation to passive house respectively plus-energy house standard with special focus on ecologic construction materials was developed in this project.
Evaluation of the quality and efficiency of state-of-the-art installed solar combisystems, potentials for improvements and measures to increase the quality
In the passive house Utendorfgasse a room–by-room temperature control was installed in 11 apartments. The experiences were evaluated from a technological and from a sociological point of view.
win wi[e]n: block development ground floor zone: Optimization of the Viennese block renewal programm as a tool for a sustainable development of street level and open (public) spaces of urban fabric
Development of the Viennese Block Renewal Program with a special focus on the ground floor zone of historical urban fabric (on the basis of the case study Block Renewal Area Ilgplatz, Vienna): sustainable restructuring and reusing of the blocks at ground level, including courtyards and street spaces- as a comprehensive planning approach.
Development of a strategy for industrialized serial production of ecological passive houses made out of renewable resources
Development of a strategy for industrialized seria. production of ecological passive solar houses made out of building materials based on renewable resources as foundation for the dissemination of sustainable solutions for the production of prefabricated houses and of single houses.
The aim of the project was to develop a continuous process chain for the energetic-economic optimization of zero and plus energy buildings. The project focused on proven and new approaches to cost reduction of nearly zero energy buildings (nZEBs) at all stages of the life cycle. The main goal was to identify the extra-costs for nZEBs, and to promote innovative approaches taking into account the cost-effectiveness for all the Stakeholders. A database containing important cost parameters and potential savings will be developed.
SaLüH! Renovation of multi-family houses with small apartments, low-cost technical solutions for ventilation, heating and hot water
New innovative concepts for heating and ventilation were investigated. Very compact heat pumps are developed in such a way that it will be possible to integrate these units into the window parapet or into a prefabricated timber façade.
EnerPHit-green concept Modernisation of a historic building with application of an aerogel insulation plaster
This demonstration project shows the comprehensive modernization of a historic building within the constraints of a regional protection zone. By using the Aerogel high-performance insulating plaster, a comprehensive energy-efficient building refurbishment had been realized without changing the outer appearance of the façade.
